It is
important to check the accuracy of the wavelength peaks using if posible a NIST
Standard like in this case.

Manufacturer send a file showing the accuracy of
the instrument against this standard and we have to verify periodically to see
if it shifts.

The
verification tell us if the deviation is more than recommend, even if the
diagnostics pass. In this case, we perform an Instrument Calibration and the
values come closer to the values from which the instrument leaves the factory.

Delta value is the difference between the nominal value and the found value.
